iPad Mini 4 Wall Mount

I wanted to use my iPad Mini 4 as a smart home controller so I started looking for wall mounts online. Most available options were prohibitively expensive and somewhat over-engineered. I wasn't too keen on prying an iPad-sized hole into my wall just so you can put a glass pane over it.
I couldn't find anything that fit my requirements so I started designing my own wall mount.

This is a pretty simple design that hides a regular wall socket mounting box with a USB power supply (see Custom section) so it keeps the iPad powered.

Since my printer only has a 20x20 cm build surface and the wall mount is well over 20 cm in length, I had to split it up into two parts. I uploaded the files for both the complete version and the two-part version.
